originally described, to even in part vinaceous, all of the males at 

 hand (5) are fairly uniformly colored, being greenish testaceous on 

 the head, body, and legs. Cheeks back of the eyes, upper edges of 

 the lateral lobes of the pronotum and the pleura fuscous; the tegmina, 

 except the dorsal field, which is pallid, quite uniformly infuscated. 

 The occiput, disc of the pronotum, and the dorsal area of the tegmina 

 seem invariably to be pallid. The genicular portion of the hind 

 femora in the males appear to be much less infuscated than in the 

 opposite sex, where it is usually quite dark. 



The following measurements can now be given: Length of body, cf , 

 19 mm., 9 , 27 mm.; of pronotum, cf , 3.3 mm., 9 , 5 mm.; of tegmina, 

 cf , 14 mm., 9 , 21 mm.; of hind femora, cT, 11 mm., 9 , 15.5 mm. 



Genus DiCHROMORPHA Morse.

 Orth., II, pp. 31, 85 (1902, 1904); Ib., Second Rept. Locust. Com. B. Aires, 

 p. 28 (1900); Ib., Ann. Carnegie Mus., VIII, pp. 444, 449 (1911)- 

 The representatives of the genus Dichromorpha all belong to the 



Western Hemisphere, where they are to be met with at suitable 



localities between, the 50th parallel north, and about the 40th parallel 



south.

 A single male specimen coming from the Rio Japacani in eastern 



Bolivia is among the material collected by J. Steinbach in February,

Nearly all of the specimens of this species are pale testaceous, rather 



than green, the prevailing color of our North American D. viridis. 



In D. australis a much larger percentage of the individuals are also 



brachypterous than is the case in D. viridis.
